Ive stayed in many Hostels. Feung Nakorn rates among the best because of its sleek modern design touches, cleanliness, open air breakfast lounge and bar, and its prime location so near to some of the temples of Bangkok, as well as the Grand Palace et al.
I stayed in a single bed room that would have accommodated two people comfortably. The bathrooms, though shared are many so you don’t feel crowded or put upon.
Feung Nakorn will be where I stay in Bangkok whether I am traveling alone or with my family
